In addition, in order to protect the waterproof layer of the bathroom wall, it should be 1.8 meters high, so it should be redone in the decoration stage. Similarly, it is also responsible for the residents downstairs.

How to make the bathroom waterproof?

1, before the toilet decoration construction, we must first determine the design of the water circuit, and we must carefully consider the possibility, feasibility and availability of the design scheme. First lay the warm, warm, water and electricity pipes and then level them.

4. Waterproof coating should be laid evenly, without brush leakage, bulging and falling off. The thickness of waterproof coating should not be less than? 1.2mm, otherwise the waterproof effect will be affected.

5. After the waterproof layer of the bathroom is completed, block the sewer of the bathroom, build a 25cm high barrier at the door, and then pour it into the bathroom? 20cm？ High water level.

After 6.24 hours, check the surrounding walls and floors for leakage. If there is leakage, repair it in time, and then do a 24-hour adverse test. If there is no leakage, the next stage of construction can be carried out.

7. It usually takes 5-7 days after the water retaining test is completed (it takes 5-7 days for waterproof coating to form waterproof film). Cement mortar protective layer is added on the waterproof coating layer, which is to protect the waterproof coating layer and to facilitate brick sticking.

Key points of waterproof construction in toilet

1. Choose a suitable waterproof material for bathroom waterproofing: One-component environmental protection polyurethane coating is a waterproof material recommended by the Ministry of Construction, which can penetrate into cracks and will not shrink after drying. This material is affordable for general decoration owners, generally from 50 yuan to 60 yuan per square meter. (Price source network, for reference only)

2. Make the floor waterproof: Before laying the floor tiles, you must make waterproof work. After laying ceramic tiles, it is necessary to ensure that there is a drainage slope on the surface of ceramic tiles, generally, 1% is appropriate, and the slope should face the floor drain, which is conducive to the discharge of wastewater.

3. Make the wall waterproof: When the bathroom takes a bath, water will splash on the nearby wall, so if there is no waterproof layer protection, the wall next door and the corner wall are easy to be damp and moldy.

4. Don't brush waterproof materials in rainy days: In order to achieve better waterproof effect, waterproof materials must be brushed three times, and the drying period of one-component environmental protection polyurethane coating is about 3~4 days. If it is brushed in rainy days, the waterproof effect will not be very good.
